RFR(T): 8234274 [BACKOUT] JDK-8204128 NMT might report incorrect numbers for Compiler area

[Daniel D. Daugherty]

Greetings,

The following fix needs to be backed out:

     JDK-8204128 NMT might report incorrect numbers for Compiler area
     https://bugs.openjdk.java.net/browse/JDK-8204128

The fix is causing failures in the stress tiers of the JDK14 CI. Please
see the info added to the following bug by Leonid:

     JDK-8234270 HugeArenaTracking.java failed assert(_size >= sz) 
failed: deallocation > allocated
     https://bugs.openjdk.java.net/browse/JDK-8234270

To keep the noise in the CI down over the weekend, I'm backing out the
fix using the following bug:

     JDK-8234274 [BACKOUT] JDK-8204128 NMT might report incorrect 
numbers for Compiler area
     https://bugs.openjdk.java.net/browse/JDK-8234274

I'm also backing out the following fix:

     JDK-8234272 ProblemList runtime/NMT/HugeArenaTracking.java

Doesn't make sense to ProblemList a test that has been deleted.

Here's the webrev for the backout:

http://cr.openjdk.java.net/~dcubed/8234274-webrev/0-for-jdk14/

I have manually verified the backout against the changeset that precedes
the changeset for JDK-8204128.

Thanks, in advance, for any comments, questions or suggestions.

Dan
